Notice for optional external slice rechargeable battery pack
DANGER
Do not attempt to disassemble or modify the optional slice battery pack.
Attempting to do so can cause an explosion, or liquid leakage from the
battery pack. A battery pack other than the one specified by Lenovo, or a
disassembled or modified battery pack is not covered by the warranty.
If the rechargeable slice battery pack is incorrectly replaced, there is
danger of an explosion. The battery pack contains a small amount of
harmful substances. To avoid possible injury:
• Replace only with a battery of the type recommended by Lenovo.
• Keep the battery pack away from fire.
• Do not expose it to water or rain.
• Do not attempt to disassemble it.
• Do not short-circuit it.
• Keep it away from children.
• Do not drop the battery pack.
Do not put the slice battery pack in trash that is disposed of in landfills.
When disposing of the battery, comply with local ordinances or regulations.
The slice battery pack should be stored at room temperature, charged to
approximately 30 to 50% of capacity. We recommend that battery pack be
charged about once per year to prevent overdischarge.
